PURPOSE:To obtain a thin battery having good discharge performance by forming a positive current collector with a thin copper plate having a cupric oxide thin layer on its one surface, which also serves as a positive terminal. CONSTITUTION:A cupric oxide thin layer 2 is formed on one surface of a copper plate 1. A separator 5 impregnated with electrolyte is placed on the thin layer 2, and a current collector 3 having a negative plate 4, which also serves as a negative terminal, is stacked thereon. The areas of the thin layer 2 and the negative plate 4 are made small than current collectors 1 and 3. An electrolyte resistant epoxy resin adhesive is placed between periphries of current collectors 1 and 3 and they are sealed by applying pressure, or a hot-melt adhesive film is placed and they are pressed. By this procedure, an adhesive layer 6 is formed and a battery is sealed. Since a thin positive electrode is formed, a thin nonaqueous electrolyte battery having good discharge performance can be obtained. |
